States, not to speak of recent annexations. I am much disposed to think so. The U. S. Department of Agriculture has, with commendable enterprise, recently undertaken the introduction of date palms into Arizona and California, and there can scarcely be any doubt of the ultimate success of the effort. There are many other palms that will thrive in a climate where dates can be grown.
Literature.—For the benefit of those who may wish further and more detailed information regarding palms a list of the most important works on the subject is appended; a few other titles are mentioned in the foot-notes.
